Produces anxiolytic effects comparable to benzodiazepines without sedation or dependence. - Sleep Optimization: Acts as a potent anti-anxiety agent, reducing stress-related insomnia without causing sedation — addressing the cognitive root of sleep disturbance rather than forcing sedation. - Immune Support: Retains immunomodulatory activity from its parent molecule tuftsin — stimulating IL-6 production, enhancing phagocytic activity, and modulating Th1/Th2 immune balance. ## Frequently Asked Questions Q: What is Selank? A: Selank (TP-7) is a synthetic heptapeptide derived from the immunomodulatory peptide tuftsin (threonyl-lysyl-prolyl-arginine) with a C-terminal Pro-Gly-Pro extension that increases metabolic stability. It is studied for anxiolytic, nootropic, and immunomodulatory effects. Q: How does Selank reduce anxiety in research models? A: Selank modulates GABAergic neurotransmission, increases BDNF expression in the hippocampus, and influences serotonin metabolism. In animal models, it produces anxiolytic effects comparable to benzodiazepines without sedation, motor impairment, or dependence. Q: Does Selank affect the immune system? A: Yes. Selank's parent molecule tuftsin is a natural immunostimulant. Selank retains immunomodulatory activity — it stimulates IL-6 production, enhances phagocytic activity, and modulates the balance between Th1 and Th2 immune responses. ## Interactive Tools - Research Calculator: https://selank-research.com/tools/dosing-calculator/ 88+ peptide protocols with reconstitution calculator, dosing phases, mechanism of action, half-life data, administration guidance, side effects, compatible stacks, per-protocol FAQs, and interactive syringe visualization.
